Historical biogeography seeks to understand the distribution of biodiversity in space and
time. The dispersal-extinction-cladogenesis (DEC) model, a likelihood-based model of …

Mexican dry environments are widespread and characterized by a rich flora and fauna in
terms of both overall species diversity and endemism, but the factors that have shaped this …

Two key processes that have been modeled in a phylogenetic comparative framework are
diversification and historical biogeography. Many questions arise on what process have …

Although microbial populations in the gut microbiome are associated with COVID-19 severity,
a causal impact on patient health has not been established. Here we provide evidence …

Background Scaling SARS-CoV-2 testing to meet demands of safe reopenings continues to
be plagued by assay costs and supply chain shortages. In response, we developed …

The microbial populations in the gut microbiome have recently been associated with COVID-19
disease severity. However, a causal impact of the gut microbiome on COVID-19 patient …

… However, for 500–1000 ka, the logarithmic trend reflects a decreasing rate of clay production
and illuviation and an almost complete stop above 1 Ma (Fig. 6a). Therefore, C/Si ratios …

We compared the phylogenetic compositions of marine planktonic archaeal populations in
different marine provinces. Samples from eight different environments were collected at two …
